大倾角工作面液压支架的稳定性分析及防倒防滑措施

Stability Analysis and Anti-dumping and Anti-slipping Measures on Greater Tilt Angle Mining Face

大倾角工作面液压支架的稳定性是大倾角煤层开采的重点和难点,针对这个特点,从倾倒和下滑2个方面分析了大倾角工作面液压支架稳定性,提出了从工作面布置开始并通过在支架与支架之间的防倒防滑装置来提高支架的稳定性,进而通过支架和输送机之间的防滑装置防止输送机下滑,提高整个工作面设备的稳定性。

The stability of the hydraulic support on greater tilt angle mining face is very important in mining process. Based on the stability discussion on tilt angle and glide of the hydraulic support, presents new ways to improve the stability of the support by assembling anti - dumping anti - slipping devices from the beginning of the mining face, and then avoid sliding of the conveyer via the devices between it and the support. The application shows that the proposed approach improves the stability of the whole mining face.
